Enviroburners' products for Metallurgical Industries are custom designed special burners. These burners are designed individually, according to each customer’s needs. All relevant conditions at the customer's facility for the burner equipment are evaluated thoroughly regarding fuels, burner capacity and process issues.

Launder and ladle burners are used for the refractory heating of receiving launders and ladles at the anode furnace outlet area. These burners are manually operated natural gas or light fuel oil burners. The construction is made of stainless steel excluding flame cone which material is heat resistant steel. Burner is self-aspirating so ambient air is used as combustion air.

Reaction shaft, Settler roof and Settler wall burners are used as start-up and/or support burners for a flash smelting furnace. Burners are utilizing natural gas or fuel oil with compressed air atomization. The burner construction is normally made of stainless or acid proof steel. Combustion air damper with actuator for air control purposes is included in a burner structure.

Anode furnace burners are used for heating the copper oxidation process and holding proper copper temperature during casting. Burners are utilizing natural gas or fuel oil with compressed air atomization. In the combustion air duct part there is a shaft which enables burner twist along a furnace. Combustion air damper with actuator is included in a burner structure.

Other special burners like hot air generator burners, CO2 –burners, preheat and start-up burners are also available for different kind of metallurgical processes. If your process needs a burner, Enviroburners will design and supply it.
